A 500-Kg Object Moves Clockwise Around a 50

question 52

Short Answer

A 5.00-kg object moves clockwise around a 50.0 cm radius circular path.At one location,the speed of the object is 4.00 m/s.When the object next returns to this same location,the speed is 3.00 m/s.
(a)How much work was done by nonconservative (dissipative)forces as the object moved once around the circle?
(b)If the magnitude of the above nonconservative (dissipative)forces acting on the object is constant,what is the value of this magnitude?
